Improve the font legibility and colours

Regarding a change in colour, subscribers have said:

"not sure if the change in font, or change in colour, but I find the very pale green, hard on the eyes. a darker green would be preferable, as it would increase the contrast with the background. old eyes are not as good as young ones."

"Ed, well done with legibility work.
But, many read one colour stronger than an other, and I find , in portfolio screen, the green for rise, reads much lighter and weaker than the red for fall. It used to be better balanced, to my eye. Totally subjective of course.”
